In stark contrast to his campaign's more recent courtship of Democrats, in January Santorum told Democrats that if they wanted to vote for a Republican, they should switch their party affiliation.
"It's the Republican nomination, not the independent nomination or the Democratic nomination," he said on the call. "If you're a Democrat and you want to be a Democrat, then vote in the Democratic primary, not the Republican. If you want to vote in the Republican Party then become one."
At the time, Santorum's main criticism was of Romney's success in the New Hampshire primary, where 53% of Republican primary participants did not identify themselves as Republicans. In the weeks following Romney's win in the Granite State, Santorum repeatedly cited that statistic in arguing that his rival's supporters was [sic] out of step with the mainstream GOP electorate. Now Santorum is hoping non-Republicans will help give him the edge in Romney's home state [of Michigan].
